A rare piece of real estate hidden in plain sight underneath a New York City church was put on the market for $7 million

A New York City church is selling the last remaining crypt in its catacombs for $7 million.

These catacombs — beneath the 200-year-old Basilica of St. Patrick's Old Cathedral — were previously off-limits, but the church recently began public tours in 2017.

The crypt available inside is one of the only remaining full-body, in-ground burial plots in Manhattan.

One lucky family can now opt to live in Manhattan for eternity — for a price of $7 million.

The Basilica of St. Patrick's Old Cathedral, a Catholic church in downtown New York City, recently put a unique piece of real estate on the market. The church is looking to sell the last remaining crypt — a sealed burial chamber — in its 200-year-old catacombs for six to seven million dollars. The crypt is estimated to fit six to nine coffins.

It's a rare opportunity — not only is this the last remaining crypt in the church's catacombs, but it's also one of the only remaining full-body burial plots left on the island of Manhattan.

Even if you're not shopping for a burial plot, you can take a look inside the catacombs. St. Patrick's Old Cathedral catacombs were previously off limits to the public, but opened for tours in 2017. The tour costs $35 a person, and is offered three times a day, seven days a week for the foreseeable future.

At over 200 years old, St. Patrick's Old Cathedral has seen its surrounding neighborhood change from the Five Points— the neighborhood notably depicted in Martin Scorsese's "Gangs of New York" — and the famous Little Italy, into one of the most expensive neighborhoods in Manhattan.

Construction began on the church in 1809, and it was once the seat of the Archdiocese, before the larger St. Patrick's Cathedral was built uptown.

Buried inside the Cathedral's catacombs include figures integral to the Catholic church, and to US and New York City history — including the Delmonico family, of Delmonico steak fame who launched the New York City fine dining scene.

John Kelly, a New York representative and boss of Tammany Hall — the infamous political group of New York City known for its corruption in the 18th, 19th, and early 20th centuries — was laid to rest there as well.

Martin Scorsese is a benefactor of the church's organ, and the baptism scene in the "The Godfather" was also filmed inside.

Anyone wishing to join the list of historical figures who have dedicated their time and money to the parish can submit interest in the remaining crypt — as long as you are Catholic and have about $7 million to spare.
